This driver uses the kernel's mac80211 subsystem.
In order to use this driver, you will need a microcode (uCode)
image for it. You can obtain the microcode from:
<http://intellinuxwireless.org/>.
The microcode is typically installed in /lib/firmware. You can
look in the hotplug script /etc/hotplug/firmware.agent to
determine which directory FIRMWARE_DIR is set to when the script
runs.
If you want to compile the driver as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/kbuild/modules.txt>. The
module will be called iwlagn.
